Compact, RMS responding, USB power sensor with a 2.92 mm male connector. All sensors are calibrated in accordance with ANSI Z540 and ISO 17025, and are first tier NIST traceable. Each sensor includes a cal certificate and data. 



  • Wide 86 dB dynamic range along with sensitivity of -60 dBm. 
  • Patented active thermal stabilization insures no drift or interruption during automated or manual measurements. The sensor is ideal for ATE applications.
  • Stable over its entire operating temperature range of 0°C to +55°C. The optional LB957A heated mounting bracket extends the lower temperature to -55°C.
  • Not affected by signal modulation. The True RMS sensor measures accurately regardless of the modulation content, for example a signal with 300 MHz bandwidth content is accurately measured.
  • Multi-path design utilizes diodes operating in square law to make measurements similar to thermal sensors, but much faster and of a much greater dynamic range.
  • Includes PMA-12 software featuring flexible power meter, logger, strip chart, analog meter, and more. The software package includes an Interactive IO program for ATE testing.
  • Advanced composite USB interface enumerates as both a USB HID device and a USBTMC device.
  • 3 Year warranty.
  • Optional SPI / I2C interface for direct connectivity to microcontrollers FPGAs.
  • Optional unattended operation makes and stores measurements with only power applied.
  • Optional security options, ideal for defense applications. 
  • Optional analog recorder output is calibrated and scalable.
